Syntax error in code snippet

Hello,
I am attaching a code snippet. Some of the variables are set in earlier code like count, arrays harr1, harr2, barr1 and barr2. The code below gives syntax errors. I am very new to Bash.

Code:
for (( i=0; i<=$(( $count -1 )); i++ ))
do
#Now read the element at barr2 location i. Also find element at barr1 at position i. Now find the position of this element in harr1. The second value we will get by reading harr2 at this position.

        first=$barr2[$i]
        search = $barr1[$i]
        for (( j=0; j<=5000; j++ ))
        do
                if [ harr1[$j] -eq $search ]; then
                        break;
                fi

        done
        second = $harr2[$j]
        echo $second
done

The error generated is in the if statement. The error says:
unary operator expected

Appreciate your help.
Thanks

NAME
syntax - Activate syntax extensions VERSION
version 0.004 SYNOPSIS
# either use syntax 'foo'; # or use syntax foo => { ... }; # or use syntax qw( foo bar ), baz => { ... }; DESCRIPTION
This module activates community provided syntax extensions to Perl. You pass it a feature name, and optionally a scalar with arguments, and the dispatching system will load and install the extension in your package. The import arguments are parsed with Data::OptList. There are no standardised options. Please consult the documentation for the specific syntax feature to find out about possible configuration options. The passed in feature names are simply transformed: "function" becomes Syntax::Feature::Function and "foo_bar" would become "Syntax::Feature::FooBar". METHODS
import syntax->import( @spec ); This method will dispatch the syntax extension setup to the specified feature handlers for the calling package. import_into syntax->import_into( $into, @spec ); Same as "import", but performs the setup in $into instead of the calling package. unimport syntax->unimport( @features ); This method will trigger uninstallations of the @features from the calling package. unimport_from syntax->unimport_from( $from, @features ); Same as "unimport", but will uninstall the @features from $from. RECOMMENDED FEATURES
o Syntax::Feature::Function Activates functions with parameter signatures. SEE ALSO
Syntax::Feature::Function, Devel::Declare BUGS
